The cancellations can be blamed in part on the bad economy, artist cancellations and perhaps headliner and founder Sarah McLachlan’s diminished public profile. When she launched the first tour in 1997, her career was in its prime. Her latest tour follows the release of her current album, “Laws of Illusion,” featuring songs about her divorce from Ashwin Sood, the former drummer in her band, and the personal milestone it represented.

The lineup at The Gorge features Erykah Badu, Sheryl Crow, Colbie Caillat, Sugarland, A Fine Frenzy and others. The concert begins at 2:30 p.m. Tickets are $33 to $107 at Ticketmaster.

The tour led by socially conscious singer-songwriter McLachlan, will aid a number of causes. To read an interview with McLachlan from Bloomberg, click here.
